What I’m pissed about is Yosemite killing trim on SSD’s. I’m still on Mavericks because of that.
The Samsung people say their products don't need Trim, OWC says their's don't either, who to believe....
My Mac Pro won't even recognize a Mavericks startup disk as bootable after installing Yosemite.
I guess the guys who write the Trim app don't want to get it signed off for the SandBox, seems like a simple thing to do but so far they haven't.. You can still install it if you want to but then who knows when the next update occurs.
I am running my SSD from a PCI card so getting the full 6G still went wonkers after Yosemite, have one installed in a Mac Mini it has the same slowdowns especially when accessing external HD's. I may attempt to downgrade the Mini and see if it will let me.
I am a real old Okie now living in a Marxist state, long story why but I joined the Army in 1957.
